Column in log table is not unique
Marco Nelissen authored
DATETIME was set as primary key but that value is not always unique.
This solution is to remove primary key constraint from column "time"
to avoid SQLiteConstraintException caused in case same DATETIME value
is attempted to be inserted into log table.
